Answer 1

你并没有通过POST或GET提交，当然取不到了
re.php:
<?php
if ($_REQUEST['passport']!='')
{
echo " <meta http-equiv=refresh content=0;url=test.php?passport=$_REQUEST['passport']>";
}
?>test.php:
<?php
echo $_GET['passport'];
?>

Answer 2

re.php:
if ($_REQUEST['passport']!='')
{
 echo " <meta http-equiv=refresh content=0;url=test.php?passport=".$_REQUEST['passport'].">";
}

Answer 3

echo " <meta http-equiv=refresh content=0;url=test.php?passport={$_REQUEST['passport']}>";这句应该这样
